@Nitschtr Wow, thanks for all the questions. I will do my best to answer as many as I can.
ATC radar sharing is easy, and will probably be available on the final public release of the network.
However, the drones are a huge project that we have only just scratched the surface of. Don't expect drones in the open beta, its more like a Phase 2 item.
The idea for drones is they will be partially AI, enough so that controllers can have fun when there are no other "real" pilots online. Hopefully over-time, they will become 100% intelligent.
Ground clamping is 100% solved. Lateral deviations due to runway/taxiway/apron differences is another issue that we have ideas for, but will be a much tougher issue to solve.
As for the more detailed ideas about shared radar... lets just put it this way, you are gonna like the end result, I promise you that ?
